The Jaws of Life, the hydraulic tool that pries a wrecked car open, came out of a drag racing parts shop. George Hurst, who made the shifters in America's muscle cars, watched a crash crew take over an hour to free a driver in the 1960s and built a rescue tool of his own. His first weighed 350 pounds; the version that followed weighed 65. Fire crews still cut people out of cars with it every day.
